Genuinely respect your students and show it:

You are in the classroom for the benefit of the students, not vice-versa. Your ability to help them understand concepts that they currently do not understand is enhanced enormously if you connect with them. No one wants to be treated like a dummy or talked down to. Connecting means giving them credit for having a brain, willing to use it and caring enough to do what it takes to get it. AND, conveying that -- not verbally, but through your body language. That means respecting them.
